Shrinkage Methods for Estimating the Shape Parameter of the Generalized Pareto Distribution
Journal of Applied Mathematics, 2023 The generalized Pareto distribution is one of the most important distributions in statistics of extremes as it has wide applications in fields such as finance, insurance, and hydrology.

Model Comparison and Calibration Assessment: User Guide for Consistent Scoring Functions in Machine Learning and Actuarial Practice [PDF]
, 2022 One of the main tasks of actuaries and data scientists is to build good predictive models for certain phenomena such as the claim size or the number of claims in insurance. These models ideally exploit given feature information to enhance the accuracy of prediction. This user guide revisits and clarifies statistical techniques to assess the calibration

How Accounting Ends: Self‐Undermining Repetition in Accounting Life Cycles*
Contemporary Accounting Research, Volume 39, Issue 4, Page 2790-2824, Winter 2022., 2022 ABSTRACT This study develops a process model of how accounting may come to an end. Grounded in a longitudinal study of a risk culture survey, this model focuses on the dynamics that underpin the repetition of accounting practices, and sheds light on two boundary conditions of successful repetition and continuation, which are in tension with each other.

Three fundamental problems in risk modeling on big data: an information theory view [PDF]
arXiv, 2021 Since Claude Shannon founded Information Theory, information theory has widely fostered other scientific fields, such as statistics, artificial intelligence, biology, behavioral science, neuroscience, economics, and finance. Unfortunately, actuarial science has hardly benefited from information theory.

Do Audit Teams Affect Audit Production and Quality? Evidence from Audit Teams' Industry Knowledge*
Contemporary Accounting Research, Volume 39, Issue 4, Page 2657-2695, Winter 2022., 2022 ABSTRACT We examine how the extent and distribution of industry knowledge within an audit team affect audit outcomes. While prior research examining the role of auditors' industry knowledge focuses mainly on audit firms, audit offices, and audit partners, audits are conducted by audit teams.

Designing an Updatable Long Term Health Insurance [PDF]
Mathematics and Modeling in Finance, 2021 In this paper, we considered the long-term health insurance as a sequence of annual health insurance policies. To improve the disadvantages of long-term health insurance, we specify the optimal contract including optimal insurance premiums and optimal ...

Stochastic comparisons of lifetimes of series and parallel systems with dependent and heterogeneous components [PDF]
Operations Research Letters, 49(2) (2021) 176-183, 2020 This work considers stochastic comparisons of lifetimes of series and parallel systems with dependent and heterogeneous components having lifetimes following the proportional odds (PO) model. The joint distribution of component lifetimes is modeled by Archimedean survival copula.

Rethinking Representations in P&C Actuarial Science with Deep Neural Networks [PDF]
arXiv, 2021 Insurance companies gather a growing variety of data for use in the insurance process, but most traditional ratemaking models are not designed to support them. In particular, many emerging data sources (text, images, sensors) may complement traditional data to provide better insights to predict the future losses in an insurance contract.

Risks, 2018 In the nearly thirty years since Hans Buhlmann (Buhlmann (1987)) set out the notion of the Actuary of the Third Kind, the connection between Actuarial Science (AS) and Mathematical Finance (MF) has been continually reinforced.
